Considering purchase of home. Walls test positive for lead paint. Walls are textured plaster in very good condition with no cracks and paint intact. Would like to have smooth, rather than textured finish. Very concerned long term about the lead, even though at present no issues regarding integrity of walls and paint. Is there a sealant or bonding agent or other product to cover lead paint. Can walls be plastered over and repainted, or would new plaster or new paint blister? Texture on walls now is deep, mottled finish. Thanks for any help.
